The more you refuel, the less you run.

This symptom can also be called lack of engine power, which is often manifested when the car is driving at high speed or uphill, especially under heavy load, the engine power is obviously insufficient and the car is stuffy, so it is impossible to speed up quickly when accelerating; Exhaust feels dull, driving is weak, and fuel consumption rises linearly.

Reasons for insufficient automobile power:

1, carbon deposition problem;

The carbon deposit here includes cylinder carbon deposit, throttle carbon deposit, spark plug carbon deposit, intake carbon deposit and so on. These positions are closely related to the power output of the engine. When there is too much carbon in the engine, it will reduce the ignition energy of the car and the intake efficiency, which will eventually lead to the reduction of engine power and the emergence of acceleration weakness and muffled sound.

2. Fuel system;

Adding inappropriate fuel label (such as 90 plus 93) will lead to the decrease of automobile output power and power; Or because the vent hole of the fuel tank cover is blocked, the fuel tank switch, fuel filter and the oil pipe between the fuel tank and carburetor are partially blocked, which can not meet the required oil supply, resulting in too thin mixture and weak engine acceleration.

3. Air inlet;

Air is one of the power sources of the engine. If the air filter is not cleaned in time for a long time, it will be blocked, and insufficient air will cause the combustible mixture to be too rich and reduce the engine power. If it is a vehicle with a turbocharger, once the turbocharger fails, even if the throttle is given, the engine will still be dull and unable to explode.
